ACL2-PC::SHOW-ABBREVIATIONS

Examples:
(show-abbreviations v w)
-- assuming that v and w currently abbreviate terms,
then this instruction displays them together with
the terms they abbreviate
show-abbreviations
-- display all abbreviations

See also add-abbreviation and remove-abbreviations. In
particular, the documentation for add-abbreviation contains a
general discussion of abbreviations.

General Form:
(show-abbreviations &rest vars)

Display each argument in vars together with the term it abbreviates
(if any). If there are no arguments, i.e. the instruction is simply
show-abbreviations, then display all abbreviations together with the
terms they abbreviate.

If the term abbreviated by a variable, say v, contains a proper
subterm that is also abbreviate by (another) variable, then both the
unabbreviated term and the abbreviated term (but not using (? v) to
abbreviate the term) are displayed with together with v.
